Dr. Thomas Ray spent years studying life in the rainforest after earning his PhD in Biology from Harvard. Years later - fascinated with evolution and the idea of replicating the evolutionary process, he founded the Tierra project - one of the first successful research projects to replicate evolutionary adaptation in a digital environment. In our interview here, we discuss Dr. Ray's views on the potential impossibility of a man-machine merger, or of machines housing consciousness. In addition, we talk about the very real possibility of biological enhancement, and Dr. Ray's concerns about how we might already be "losing our humanity." For more, visit: SentientPotential.com
